The project is one of 70 around New Zealand in Waka Kotahi NZ Transport Agency's Innovating Streets for People programme. It is 90 per cent funded by the agency, and 10 per cent by South Taranaki District Council.
Waka Kotahi aimed to reduce driving, grow public transport, walking and cycling and create a safe, healthy, low carbon transport system, regional transport systems manager Ross I'Anson said.
The Innovating Streets programme is also about making towns more welcoming and inclusive. The community and the heavy haulage industry were both involved in the design for Waverley.
The project is a trial. Its value will be assessed and the changes will continue if people like them.
Construction, which is taking place overnight from 7pm to 5am, has been slowed by bad weather.
